Suppose you are given 150 mg of an unknown mixture that contains three compounds, and you are told to separate the compounds using column chromatography, using alumina as a stationary phase. How would you decide what solvent or solvent system to use?
You take 1 ml of your sample and dialyze it in 1000 ml of buffer. At the end of dialysis what is the concentration of (NH4)2SO4 in your sample. How could you further lower the (NH4)SO4 concentration
What is the specific heat for the metal? Express your answer with the appropriate units. B) The molar heat capacity of silver is 25.35 J/mol
N-Methyl-2-pyrrolidone is an aprotic solvent used in many industrial processes. Draw the structure of the product formed when it is heated with strong aqueous acid 6MHCI, H20 and heat.
If 2.50 g CuSO4 are dissolved in 8.0 x 10^2 mL of 0.25 M NH3, what are the concentrations of Cu2+, Cu(NH3)4^2+, and NH3 at equilibrium
An equilibrium mixture contains 0.810 mol HI, 0.170 mol I2, and 0.200 mol H2 in a 1.00-L flask. What is the equilibrium constant for the following reaction
Express in terms of P, V, T, C_p, C_v and their derivatives. Your answer may include absolute values of S if it is not a derivative constraint or within a derivative.
The concentrated sulfuric acid is 98.0 percent h2so4 by mass. the density of the solution is 1.83 g/ml. the molar mass of h2so4 is 98.08 g/ml.What is the mass of h2so4 in 100.0g of concentrated sulfuric acid solution?
Let us assume that we are working with a vesicle created from a biological membrane and wish to determine whether the various proteins are integral or peripheral and exposed to which side of the membrane
Given that the radius of the O2- ion is about 140 pm in most oxides, calculate the radius of Mg2+, in pm. Your solution should include a sketch one face of the unit cell of MgO to show how the edge length of the unit cell is related to the ionic r..
The extent of fragmentation for ionic compounds can be derived by comparing the molality expected if no dissociation with what is actually obtained from experiment.
